I bought 2025 Silverado High Country with Super Cruise. It keep displaying error message on the instrument cluster “ Service Driver assist System” Also These are photos of the phone not detected in the myChevrolet app, and the infotainment system showing an ''unexpected error code'', there also a photo of IPhone 16 pro max showing a ''weak connection signal''. The vehicle's Blind Spot monitor does not light up mostly on the passenger side when passing a vehicle and sometimes when a vehicle is approaching from behind. Same as right driver side, but mostly the passenger left side is the issue, also when in Super Cruise mode the left Driver side ''Auto Lane Turn signal'' does now always initiate.
The Infotainment system shows error always, also the iPhone 16 pro max is never detected after a day of being paired, If go to

It says "unexpected error "
Also the phone not being detected so it does not unlock the infotainment system. You always have to hand input the infotainment system code.
Phone does not Auto-unlock on start up screen , if you unpair and disconnect phone and repair device , it will work for one day correctly, after that day , it stop working and phone goes back to not detected. Anyone has this issue. The dealership is calling it an communication issue, it not throwing any hard codes, the dealership is in talk with GM, basically they don’t know the problem nor the fix as of now, it been there twice for this problem, they told me to drive until they get more information, it has only 4000 miles on truck.
